Congrats Laughlin Motorsports!

We’d like to Congratulate Matt Laughlin of Laughlin Motorsports for their Class 10 win at the HDRA ” Rockin at the River” this past weekend. This was the 1st race in the Class 12 to Class 10 conversion. Not much test time on the new suspension but they seemed to have figured it out and brought home the Class 10 Penhall Cholla for the win. Thanks for making us look good.

Progress on the Ultra 4

The Ultra 4 is currently a roller and moving ahead at top speed while we make sure we still pay attention to detail. The Ultra 4 was recently taken to the Off Road Expo in Pomona Calif. and stirred up quite a bit of attention. It was featured in the Goodyear Tire booth.

The Ultra 4 is being built for one of the top racers in the King of the Hammers series. Ben Naiper of Australia finished 2nd in last years Ultra 4 series. This car will have it’s debut at the 2013 King of the Hammers in Johnson Valley February 1- 8 . This is our first time building a car for the Rock Crawling community and we’re very excited to see how it stacks up against some of the top competition. We’re excited  to have been asked to do this build for such a top notch driver.
